Αν συγκρίνεις τις δύο τιμές, αυτή είναι καλύτερη.

Αν means if. It introduces a condition:

• Αν συγκρίνεις... = If you compare...

It is the normal word used in Modern Greek for if in sentences like this.

Συγκρίνεις is the 2nd person singular form of συγκρίνω = to compare.

So it means:

• you compare
• you are comparing
• after αν, effectively if you compare

The ending -εις already tells you the subject is you (singular).

Because Greek often leaves subject pronouns out when the verb ending already makes the subject clear.

So:

• συγκρίνεις already means you compare

You could add εσύ for emphasis, but it is not necessary:

• Αν εσύ συγκρίνεις... = If you compare... with extra stress on you

Because τιμές is the direct object of συγκρίνεις, so it appears in the accusative plural.

Breakdown:

• τις = feminine plural accusative article
• δύο = two
• τιμές = prices / values

So τις δύο τιμές means the two prices or the two values.

Greek often keeps the article with a specific set of things, so τις δύο τιμές is very natural for the two values/prices.

Τιμή can have several meanings depending on context, such as:

• price
• value
• honour

In this sentence, the natural meanings are price or value, because you are comparing two of them.

It refers to an understood feminine singular noun, most likely η τιμή.

So αυτή here means:

• this one
• this price
• this value

Greek often leaves the noun out when it is obvious from the context.

Because the noun it refers to, τιμή, is feminine.

In Greek, demonstratives and adjectives must agree with the noun in:

• gender
• number
• case

So if the understood noun is η τιμή:

• αυτή must be feminine singular
• καλύτερη must also be feminine singular

For the same reason: it agrees with the understood feminine noun τιμή.

Here the hidden structure is basically:

• αυτή η τιμή είναι καλύτερη
• this price is better

Since τιμή is feminine singular, καλύτερη must also be feminine singular.

Yes. Καλύτερη means better.

It comes from the irregular comparative of καλός / καλή / καλό = good.

Comparative forms:

• masculine: καλύτερος
• feminine: καλύτερη
• neuter: καλύτερο

So here:

• αυτή είναι καλύτερη = this one is better

Because Greek often omits the noun when it is easy to understand.

English often says:

• this one is better

Greek can simply say:

• αυτή είναι καλύτερη

The idea of one is understood from the context, especially because τιμή has already been mentioned.

Yes, depending on context.

In many everyday situations, αυτή can be translated as:

• this one
• sometimes that one

If Greek wants to point more clearly to that one over there, it can use εκείνη instead.

So here, αυτή is best understood as this one, but context could affect the English translation.

No. Greek word order is more flexible than English word order.

This sentence:

• Αν συγκρίνεις τις δύο τιμές, αυτή είναι καλύτερη.

is a natural, neutral way to say it.

But Greek can move things around for emphasis. The original order is clear because it gives the condition first and then the conclusion.
